Does anyone have some recommendations for measuring total end-to-end latency
(by which I mean: the time between person A saying something and person B
hearing it) when there are both SIP and PSTN/analogue/mobile legs in the call
Person A has a SIP phone registered to Asterisk, which has a SIP trunk to a
connectivity provider, who has connections to PSTN (analogue landline)
connectivity providers and to mobile network (Vodafone, Orange, etc)
Person B might answer the call on an analogue landline telephone.
Person C might answer the call on a mobile phone (perhaps on its home network,
perhaps roaming on a foreign network).
Is there any way to measure total latency of calls between A and B or A and C?
Thanks in advance for any ideas / suggestions.
